backfires

So after solving my cooling problem now a new thing came up. A month ago when I was reving my bike for fun or just to show off it didnt have any problem(had no backfires), running normally, reving up normally. But like a week ago when I do the same, even if while moving, pulled clutch and full...

I posted this in my new to FE570 thread but thought I might get more eyes on it here. I have a brand new issue. I think it's a fuel issue based on some research and tips from Rainerio on here. About 5 times in a few hours, mostly on downhills in 2nd gear and engine breaking or just...
